BY 6 d ATTORNEY Patented Jan. 12, 1932 UNITED STATES PATENT OFFICE? ALBERT RANDALL, F WHITESTONE, NEW YORK HINGED FASTENING DEVICE Original application filed January 9, 1930, Serial No. 419,616. Divided and this application filed July 29,

' 1931. Serial No. 553.836.

- My invention relates broadly to hinged fastening devices for papers and thelike and more particularly to a construction of hinged fastening device for attaching a sheet-like member to a supporting surface in such manner that both sides of the sheet-like member may be readily inspected.

This application is a division of my application Serial No. 419,616, filed January 9,

19 30,f0rhinged fastening device. H

One of the objects of my invention is to provide a construction of hinged fastening device having means for detachably receiving a sheet-like member in predetermined 1.) position with respect to a supporting sheet.

Another object of my invention is to provide a construction of hinged fastening device particularly adapted for use in stamp albums for detachably mounting covers or stamped envelopes in an album in predetermined position.

. Still another object of my invention is to provide a construction of hinged fastening device for stamped envelopes for use by col- 26 lectors in mounting stamped envelopes within a stamp album, wherein means are provided for. detachably mounting exhibit envelopes in predetermined position with respect to the pages of the album, the detach 3U able means being suspended through a-laterally extending slot in a securing tab adapted to be secured to a page of the album.

A further object of my invention to provide a construction of hinged fastening device comprising a securing tab which is laterally slotted for the passage of a clip mem! her having supporting parts extending in opposite directions on both sides of the slotted portion of the securing tab and adapted to pivot about the tab for hingedly supporting a flat sheet by means of the clip member.

Other and further objects of my invention reside in the construction ofhinged fastening device, as set forth more fully in the specification hereinafter following by refervelope; Fig. 2'is a detailed front elevation of my improved hinged fastening device; Fig. 3 is a detailed perspective view showing the securing clip of my invention as illustrated in Fig.2 about to be positioned within the attachable fastening device; Fig. 4 is a detailed perspective view of the fastener shown in Fig. 2; Fig. 5 is a detailed front elevation of a modified form of hinged fastening device embodying my invention; Fig. 6 is a perspective view of the parts of the hinged fastening device shown in Fig. 5 where the clip is about to be assembled within the hinged attachment member; Fig. 7 is a perspective view of the modified form of at tachment device illustrated in Fig. 5 as it is finally assembled; Fig. 8 illustrates the form of fastening device shown in Figs. 5, 6 and 7 having guard means enveloping the parts of the clip for preventing creasing of the exhibit envelope; Fig. 9 is a cross-sectional view taken through the guard means on line 99 of Fig. 8; and Fig. 10 is a perspective view of each of. the guard means illustrated in Figs. 8 and 9.

,With the increasing use of air mail'envelopes there has come a demand by stamp collectors for means for properly preserving specimens of exhibit air mail envelopes. The usual method of mounting stamps in stamp albums by means of a gummed paper hinge has been found to be impracticable for the mounting of air mail envelopes which are known to stamp collectors as covers or a:

an entire. The single paper hinge ordinarily employed in the mounting of stamps has not been practicable for the mounting of en tire envelopes due to the comparative mass of the envelope with respect to the stamn which is usually mounted upon a 1 paper hinge; WVhen a plurality of paper hinges are used for mounting an entire, difficulty arises in the proper alignment of the several paper hinges and buckling and tearing of the hinge often results under the continued movement of the envelope as the pages of the album are leafed.

My invention provides means for mounting the entire air mail envelope with respect to the. pages of a stamp album ina manner which facilitates the quick and easy inspection of both sides of the envelope for observing the cancellations appearing on one side of the envelope and the air mail stamps and post office inscriptions appearingon: the front of the envelope. I provide a construction of hinged fastening devices having suflicient rigidity to properly position an exhibit enexhibit stamps. I have illustrated in plan viewthe page of a stamp album on which a cover, an envelope, or, as a-postmarked envelope specimen is lrnown amongstamp collectors, an entire;2 is hinged ly mounted. The fastening means is illustrated as comprising two parts, part .3 of which constitutinga tab is secured to the pageof the stamp album and part4 of which constitutinga clip isarranged to engage the envelope 2. In Figs. 2, '3 and 4 I have shown the fastening device of my invention wherein the securing portion 3 of the fastening device which engages the page of the album shown at Ihas a central diametrically extending slot '5' formed therein. -'A resilient wire member" is illustrated at 4 for forming the two ,adjacent loops with ends 6 and 7 projecting therefrom, the parts of the resilient wire .4 being adapted to engage opposite sides of the envelope 2. The manner of assembling the hinged fastening device is shown more clear ly in Fig. 3 where the resilient wire member 4 is passed through the central diametrically.

extending slot 5 with the projecting portions 6 and 7 fitted in the diametrical fold 8 of the securing portion The'inner faces of the securing means '3 are united by suitable glue or mucilagef forming when folded a semicircular member which is readily attachable.

to the page of the album 1. The resilient Wire 4; is free'to revolve through an angle of substantially 180 degrees -.enab'ling t-he en'- vele'pe carried thereby to be reversed in P081 tion in theal-bum, thus allowing inspection of" both :sides of the envelope. The resilientwire 4 looped centrally as indicated at 4a, Lthus cated at 16 is formed from a circular sheet of material which is folded diametrically, the sheet of material being apertured at 17 and 18 on either sideof a tongue 19 which is cut from the material of the circular sheet 16. The fact that the tongue 19 is severed from the material of the tab 16 enables the partsof the clip device to be inserted through the tab and suspended with respect to the sheet to which the hinged fastening device is attached. Theclip device is shown as comprising depending resilient jaws 20 and 21 which extend through the central slot in the tab 16 and engage opposite sides of the :envel0pe2. A bar member 22 extending diametrically of thetab 16 is welded or otherwise secured to the upper portion 23 of the spring clip for supporting thespring clip in position for angular movement with respect t0 the tab 16 and the surface 1 on which the tab is mounted.

In the case of rare specimens which it is desired to preserve, I further protect the cover or envelope against creasing under the action of the resilient jaws 20 and 21 by means of the enveloping covers'26 and 27, as

shown in Figs. 8, 9 and 10. The enveloping covers are made of celluloid or other mate struct the enveloping covers of a single sheet of material properly apertured. to permit the insertion thereof upon the spring aws.

As heretofore noted the parts of the paper tab 3 which fold adjacent each other are united by a coating of mucila-ge which is suitably moistened when the hinged fastening device is placed in use. The rearsurface of the tab is also coated with mucilage to permit the attachment of the tab to the page of the album. The front semiecircular portion of the tab does not have a mucilagecoating thereon and is therefore free to be pressed by means of'the finger againstthe surface of the supportingpage in an album. 7 The fastening device of my invention may be employed for a variety of purposes, such as the mounting of advertising cards, the mounting of restaurant menus, and the attachment of advertising matter to window panes. The device is also very practical as a substitute for thumb tacks which are mounted on bulletin boards.

I have found the attachment device of my invention in its various forms extremely practical in its construction, and while 1 have described certain preferred embodiments of my invention, I desire it to be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.
